srncrcATIoN forming pert of Letters Patent Ne. 531,476, dated Deeember 25, 1894.

Applioationfiled May 22, 1894. Serial No. 512,067. (No model.)

objects of my invention is to produce an extremely'simple apparatus of this class which holds the anzcsthetic in such a way that it cannot well be separated, which also carriesV the anaesthetic in such a waythat nothing but the Vapor can possibly be introduced into the patient, which is constructed in such a manner that it may be conveniently operated with one hand, which obviates the necessity of using masks, nhalers, and analogous things, and Which enables aneesthesia to be perfectly maintained during an operation, thus rendering the operation easy to both the patient and surgeon, and to construct the device in such a Way that it is extremely cheap, simple and durable.

To. these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed. Reference is to be had to the accompanying drawings, forming a part. of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure 1 is a perspective View of the apparatus embodying my invention; and Fig. 2,

is a central Vertical section of the same.

The device is provided witha holder to contain the receptacle in which the antesthetic is held, this holder comprising the bands 10, the lower one of which is turned under, as' shown at 10a to form a base flange, the strips 11 connecting the two bands, the side arms 12 projecting from the bands 10, the end rings 13\on the arms to support the bulb 14, and the thumb ring 15 on one of the strips 11. The bulb 14: is of the usual kind, being'made of rubber having an inlet at one end and an outlet at the other, and needs no detailed description.

A bottle 16, or other suitable receptacle, is

held in the holder and is adapted to contain the anaesthet'ic, the bottle or receptacle having within it absorbent cotton, sponge or other suitable material which absorbs the anzesthetic so that only the Vapor can be ejected, and this arrangement also prevents the antesthetic from being spilled. The bottle is closed tightly by a stoppe'r 17, through which project parallel tubes 18, one of which serves as an inlet for air and the other as an outlet for anwsthetic Vapor,'these tubes being provided with stop cocks 19, and one of them connects, by a pipe 20, with the bulb 14 while the other is connected with a fiexible pipe 21 which is pointed at its free end and is provided with a side opening 22 through Which the Vapor issues. i

It will beseen that the apparatus may be grasped in one hand, the `thumb or finger being thrust through the ring 15, and the bulb 14 squeezed and released so as to force air into:the bottle, and the anaesthetic Vapor is thus forced out through the tube 21. It will also be seen that the tube 21 may be of any length and it may be inserted in any orifice of the head, usually in the mouth or nose, lbut if an operation is to be performed on the nose or mouth the tube Vshould be extended into the lower pharynx and in any event the device may be worked so that a constant supply of the anzesthetic Vapor is introduced into the patient and a perfect aneesthesia is maintained.

The inner ends of both of the tubes 18 are made to terminate a short distance from'the bottom of the stopper. This construction prevents the liquid anzesthetic in the form of spray orv wet Vapor from being emitted from the instrument, as the inner ends of the tubes are in contact only with the dry Vapor in the upper part of the receptacle.

It will be observed that the shape of the tube enables it to readily enter the head and, as the opening is in the side, it is not easily Iclogged.

Having thus described my invention, I

with a stopper and pipes held in the said stopper and provided with stop cocks, of a holder for said receptacle, an air bulb carried by said holder and connected with one ot the pipes leading into the receptacle and a fiexible discharge tube connected with the other pipe and having a closed end and a side opening, both of said pipes passing through the stopper being made to terminate near the inner end thereof and above the absorbeit nlaterial held in the receptacle, whereby only the dry aneesthetic Vapor contained in the upper part of the receptaele is emitted from the device, substantially as described.

2. A device for administering anzesthetics, comprising a holder having upper and lower bands and connections between the two bands, the said holder being provided with a thumb ring on one side and having projecting arms on the opposite side terminating in rings, of a receptaele held in the said holder and provided with a stopper, pipes extending through the stopper and terminating near the inner end thereof for the purpose set forth, a stop cock for each of said pipes, an air bulb having its ends removably held in the rings on the holder, a tube connecting the upper end of the air bulb with one of the pipes extending through the stopper, and a flexible discharge tube connected with the other pipe, substantially as described.

EDMOND SOUCIION.
